======================================================
SRU Justification:
1. Impact of bug: qemu segfaults when emulating some arm architectures, unless '-m X' (for some low X) is specified.
2. How was the bug addressed: a patch is added which lowers the default RAM size for ARM architectures.
3. Patch: See the linked sources trees (for lucid and maverick)
4. TEST CASE: 'qemu-system-arm -M versatileab -kernel zImage
5. Regression potential: if there are users whose arm systems require a larger RAM size, they could experience regressions without specifying '-m 356'. This is very unlikely.
======================================================
Binary package hint: qemu-kvm
The following commands close immediately with segmentation fault:
qemu-system-arm -M versatilepb -kernel zImage
qemu-system-arm -M versatileab -kernel zImage
The following does not cause segmentation fault:
qemu-system-arm -M versatilepb -kernel zImage -m 128M
qemu-system-arm -M versatileab -kernel zImage -m 128M
zImage is a linux kernel image for ARM that worked with previous versions of qemu-system-arm, but the error is independent from the -kernel option, because it segfaults using any file.
The option -m 128M should be the default, and in older versions it worked the same with and without it.
